AN = Analog input or output; TTL = TTL compatible input; HV = High Voltage; OD = Open Drain; XTAL = Crystal; CMOS =
CMOS compatible input or output; ST = Schmitt Trigger input with CMOS levels; I²C^TM = Schmitt Trigger input with I²C.
Default pin assignment for P2B, T3CKI, CCP3 and CCP2 when Configuration bits PB2MX, T3CMX, CCP3MX and
CCP2MX are set.
Alternate pin assignment for P2B, T3CKI, CCP3 and CCP2 when Configuration bits PB2MX, T3CMX, CCP3MX and
CCP2MX are clear.
